APPLICATION TECHNICAL MANUAL OF XINHAI MINING MACHINERY PRODUCTS ■ CLASSIFYING XCI Xinhai Hydrocyclone Principle Under the effect of pressure, pulp enters the shell through the square feeding pipe in involute direction, and does the rotary motion in the shell. The coarse or the dense particles get to the periphery of rotary current because of the centrifugal force and turns into riffling through the spigot; because of the smaller centrifugal force, the fine particles will be in the middle of the rotary current, move up along with flow, and finally become overflow discharged from overflow pipe. XCI hydrocyclone is a kind of new high effective hydrocyclone with adjustable feeding port and spigot. It is designed by Xinhai with professional design theory such as CFD model and 3D model analysis system and has reached the world advanced level. It’s more suitable for classifying and dewatering. Three kinds of cyclone: 10 ° , 15 ° and 20 ° are available. 团 集 海 Features Because of the three dimensional snail type feeding structure, it achieves circumferential and axial feeding, eliminates the turbulence interference around the overflow pipe which formed up after material getting into hydrocyclone, speeds up the rotary stream that coarse material flows to the underflow port, avoids violent spin during the feeding process, and improves the efficiency of classification; The square tube feeding type makes material get closer to the inner wall, makes the feeding resistance to the smallest, provides the biggest divergence to material, and causes the smallest damage to the flow box; Unique cone adjusting device at the feeding inlet can adjust the size of hydrocyclone’s entrance quickly, and therefore improves the efficiency of classification; 鑫 Wedge cone-adjusting valve is a replaceable part of the inlet pipe, and unnecessary to change the whole rubber liner of hydrocyclone; Xinhai super wear-resistant rubber lining has excellent wear resistant property. It can reduce the cost greatly, keep the shape and size of inner flow passage for a longer time, and maintain a stable classification efficiency; We can provide die pressing super wear-resistant rubber liner and cold bonding super wear-resistant rubber liner, both with long service time; Customized cyclone selection software realizes rapid and accurate selection .
